An elastic bandage comprises a knitted or woven fabric containing both inelastic and elastic yarns in which the ratio of inelastic yarns to elastic yarns is from 1:1 to 12:1 and in which the bandage achieves an effective compressive force at an extension of between 20 to 60% after which any further extension of the bandage is accompanied by only a small increase in compressive force. Suitable polymers for the elastic yarns include block copolymers such as styrene-butylene-ethylene-styrene block copolymers. Woven or knitted elastic bandages made of such yarns exhibit good stress retention properties. |
